3,152,668 ANCHOR ARRANQEMENT FOR THE PGM?. END 6l? A 'GUY WIRE Donald Il. Smith, Sleepy Hollow Manor, lll., assigner to Reliahle Electric Company, Franklin Park, Bl., a corporation of illinois Filed Feb. 23, 1%1, Ser. No. 91,238 4. Claims. (Cl. 189-31.1)

This invention relates to an improved anchor arrangement for the pole endof a guy wire.

Heretofore, there have been two principal means of anchoring a guy wire to a poleg'in one the guy wire is merely wrapped around the pole and secured to itself, and in the other a fitting is used that requires a long bolt which extends through the pole, a standard deadend, in-

cluding yoke and bail, often being used to connect the guy wire to the itting.

The present invention provides a better anchoring a1'- rangement than either of the two prior art arrangements,

for the reason that it is easier to install in the sense that the guy wire may be tensioned incident to the act of installation. Also, it is considerably cheaper than the above mentioned iitting because it does not require the use of ,which the guy wire itself serves as the tension member which extends through the pole.

Other objects, features and advantages will become apparent as the description proceeds.

With reference now to the drawings in which like reference numerals designate like parts:

FIG. 1 is an elevation, partly in section, showing a pole and guy wire arrangement which embodies my invention;

FlG. 2 is a longitudinal section ofthe anchor cartridge;

j FIG. 3 is a vertical section taken along line v3 3 of FIG. 2;

FIG. 4 is a horizontal section taken along line 4 4 of PIG. 1;

FIG. 5 is a View similar to FIG. 1 but showing a .'modication;

FIG. 6 is a 'horizontal section taken along line 6--6 of FIG. 5;

FIG. 7 -is a perspective View of the thrust tting shown FIG. 8 is an elevation thrust fitting.

With reference now to FIG. l, a pole 1t) has its lower end embedded in the earth 11, and is braced in one direction by a guy wire 12. f

The lower end of the guy wire is anchored in the earth by means of anranchor block 13,I an anchor rod 14 and a deadend cartridge 15. The latter is a wire gripping device of the type shown in Iugle Patent 2,288,138, for example, or in Cook Patent 2,180,977, in which the car.- tridge 15 is provided with a yoke 16 and a bail 17, the bail extending through the eye 18 ofthe anchor rod 14.

showing a modified type `of This arrangement makes for a very secure ground anchor for the guy wire.

The pole 10 isprovided vwith'a horizontal hole 20 An anchor` cartridge 22, lwhich is in the form of a jaw United States Patent() ice type wire grip, is mounted on the projecting end portion 2l and serves as an end anchor for the pole end of the guy wire 12. A suitable washer 23 is disposed between thev anchor cartridge 22 and` the pole lil. As ,shown in FIG. 4, the Washer 23 is preferably in the form of a curved square plate which conforms generally to the curved surfaceof the pole.

This arrangement in which the hole 20 is at an angle to the span 34 of the guy wire results in a bend 24 in the guy wire 12at the proximate pole surface, and in order to prevent the guy wire from cutting into the pole as the wire is tensioned, a thrust fitting 25 is positioned between the guy wire 12 and the pole 10. This thrust titting is preferably in the form of a flared aluminum tube (FIG. 7), the tube being disposed within the hole 2%, and having a flared portion 26 which takes up the thrust of the guy wire at the bend 24.

Y The anchor cartridge 22 is shown in FIGS. 2 and 3, and is in general similar to the deadend cartridge of the aforesaid l'ugle Patent 2,288,138, or Cook Patent 2,180,977, except for the shell. The anchor cartridge 22 comprises tapered jaws 27 and a spring 28 which are located Within a cylindrical shell Z9. The shell is provided with a ltapered bore 30 at one end which cooperates with the taper of the jaws 27 to urge the jaws inwardly into grip ping relationship with theguy wire 12 when tension is applied to the guy wire. The tapered jaws 27 and the spring 28 are confined within the shell 29 by means of a washer 31- and staking 32. The arrangement and the operation are the same as pointed out in the aforesaid patents. However, the shell 29 is in the form of a cylinder having, at the smaller bore-end thereof, an annular l end surface 33 of substantial dimensions, and which is `disposed in a plane perpendicular to the shell axis. Thus,

a substantial area is provided for abutting the Washer 23 so that the tension of the guy'wire may be transmitted to the pole 10.

In operation, after the anchor block 13 has been installed, and the guy Wire connected thereto by means of the deadend cartridge 15, the hole 20 is drilled through the pole 10, Ithe thrust fitting 25 inserted into the hole 20, the guy wire 12 threaded through the thrust fitting 25 and the hole 20, and then the washer 23 and the anchor cartridge 22 are applied to the projecting end 21 of the guy wire. The projecting end is` preferably of suitable length to permit installation of a Wire tensioning device, andl as the guy wire 12 is drawn taut and tensioned, the anchor cartridge 22 is pushed forwardly into tight enf gagement with the washer 23 and the pole 10. A feature of the anchor cartridge is that there is no play or slack incident to its operation, with the result that when the wire tensioning device is released, the same stress will be transmitted to the pole through'the anchor cartridge 22 and washer 23. After removal of the wire tensioning device, the excess length of the projecting end portion may be cut off.

It desired, other types of thrust fittings can be used in place of the ilared aluminum tube 25, such as the grooved block 40 but the advantage of the flared tube 25 is its low cost.

An alternative arrangement is shown in FIG. 5 which dispensesrwith the thrust fitting 25. Here a hole 35 is drilled in the pole 10 at an acute angle to the pole axis, and in substantial alignment with the span 34 of the guy wire 12. The same anchor cartridge 22 is provided for-.the projecting end portion 21' of the guy wire, but

@the washer is in the form of a block or casting 36 which has a surface 37 which is perpendicular to the axis of the inclined holeSS. Thus, the anchor cartridge 22' may be firmly seated onthe washer 36 so that the tension of the guyk wire may be transmitted to the pole 10-` The washer may include one or more prongs 38 which serve to maintain the same in centered relationship with respect to the pole axis. Since this arrangement results in no bend in the guy wire at the proximate pole surface, no thrust fitting is required. Similarly, if the parts are not in exact alignment so as to result in aslight bend, Ythere will still be no appreciable amount of thrust, although a suitable grommet may be utilized at the lower end of the hole 35, if desired.

Although ronly preferred embodiments of my invention have been shown and described herein, it will be understood that Various modifications and changes may be made in the constructions shown without departing from the spirit of my invention as pointed out in the appended claims.

I claim:

An anchor arrangement for 'the pole end of a guy wire comprising a pole having a hole formedV therein and tapered jaws located within said tapered bore and cooperating therewith, a spring urging said jaws toward the` smaller end or" said tapered bore, and means confining said spring Within Ys aid shell, said shell providing, at the smaller bore-end thereof, an annular end surface or" substantial radial thickness for engagement with said washer means, and for transmitting the tension of the guy wire engaged by said Wire grip 'to said washer means and said pole to provide an end anchor for said guy Wire.

2. An anchor arrangement as claimed in Vclaim 1 in which the span of said guy wire and said hole are disposed at an angle to each other so that a bendis produced in said guy wire at said proximate pole surface, and a thrust tting disposed between said guy wire and said proximate pole surface.

3. An anchor arrangement as claimed in claim 2 in which said thrust iitting is in the -forrn of a tube which is flared at one end.
